simplest possible telescope
Galileo turned a refracting telescope, which uses lenses to gather and focus light, skyward in 1610. This allowed him to make groundbreaking astronomical observations such as the moons of Jupiter and the phases of Venus.
A radio telescope uses an antenna and receiver to detect radio waves emitted by astronomical objects. These telescopes are essential for studying objects that emit radio waves, such as pulsars, quasars, and radio galaxies.
A telescope that uses one or more mirrors is called a reflecting telescope. Light is collected and focused by the primary mirror, which then reflects it to a secondary mirror that directs it to the eyepiece or detector. This design allows for larger apertures and better image quality compared to refracting telescopes.
The telescope you are referring to is likely a refracting telescope. In a refracting telescope, light enters through an objective lens which bends the light rays to a focal point where the image is formed. This type of telescope is commonly used in astronomy and for terrestrial viewing.
x-ray
X-ray telescopes use grazing incidence mirrors to reflect and focus high-energy X-rays, which would be unable to be focused using traditional optical lenses. This design allows for better resolution and sensitivity for observing celestial objects that emit X-rays.

A reflecting telescope.
A refracting telescope is a type of telescope that uses a lens as its objective to form an image. This is different from other type of telescopes because it has a objective lens.
A refracting telescope uses two lenses - an objective lens to gather light and focus it and an eyepiece lens to magnify the image.
